Square Yards to Square Kilometers

Convert square yards (yd²) to square kilometers (km²). Both measure surface measurement, and the conversion comes up in real estate, farming, construction work.

The Formula

`` square kilometers = square yards × 8.3612736e-7 square yards = square kilometers × 1195990.0463 `

One square yard is 8.3613e-7 square kilometers, and one square kilometer is 1,195,990.05 square yards.

What Each Unit Is

Square Yards (yd²) — nine square feet, or 0.836127 square metres. The imperial unit for carpet, turf and concrete.

Square Kilometers (km²) — one million square metres. The metric unit for regions, cities and land cover.

A Sense of Scale

  • Carpet is priced per square yard
  • A small rug is about 4 yd²
  • Central Park is 3.4 km²
  • Manhattan is 59 km²
  • Greater London is 1,572 km²

Precision

The factor 8.3612736e-7 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.

In Code

`javascript const squareYardToSquareKilometer = (value) => value * 8.3612736e-7; ``

How Many Decimals Do You Need?

Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 yd² with the factor truncated at each decimal place:

Decimals keptFactor137 yd² becomesError
000100.0000%
100100.0000%
200100.0000%
300100.0000%
400100.0000%
A rule that holds for any conversion: round once, at the end. Rounding the factor and then multiplying compounds the error through every subsequent calculation, while carrying full precision and rounding the final answer does not.

The right number of significant figures is set by your input, not by the converter. If you measured square yards to three significant figures, the answer in square kilometers is only good to three — writing more digits claims precision the measurement never had.

Other Conversions From Square Yards

The same value in every other unit this converter supports for area:

1 yd²3.2283e-7 mi²Square Miles
1 yd²2.0661e-4 acAcres

Chaining conversions works — square yards to metres to feet gives the same answer as square yards to feet — but each step rounds, so a chain of three conversions carries three roundings. Convert directly where a direct factor exists.

Frequently Asked Questions
